offsetGet()

{@inheritDoc} If an matching system environment variable is set, then the value of that environment varible is returned instead. Any set value on this array will have no effect in that case.

public offsetGet(mixed $offset) : string|int|null

A matching system environment variable is defined as follows: Each uppercase character in $offset (which should be in camelCase notation) is prefixed by an underscore character, before converting the resulting string all into uppercase and prefixing it with CLX_CONFIG_. Where is substituted by $prefix passed to the constructor of the object. Some examples follow. If $offset is 'cacheUserCacheMemcachedConfig' and object has been initialized with an empty $prefix, then the matching environment variable is: CLX_CONFIG_CACHE_USER_CACHE_MEMCACHED_CONFIG Or if $offset is 'host' and the object has been initialized with $prefix set to 'DB', then its matching environment variable is: CLX_DBCONFIG_HOST

Parameters
$offset : mixed
Return values
string|int|null —

Returned type depends on option identified by $offset. If $offset is undefined, then null is returned. Important: this will change in the future. Therefore you must not depend on that. Instead use static::exists() to check for the existance of an option.
